Glad you got it working,
One thing I found there is not a lot of room underneath a 12" DOB so my direct drive is very difficult to implement on the centre axis.
I have though successfully created a direct drive from the outer DOB plate but my encoder resolution is way too high now, something in the range of 200,000 steps so it is off to get a lower res encoder. I will consider the ones purchaced recently but I am also looking at some new selectable PSR encoders so I can adjust them. It cannot be mounted directly like other encoders as it has a floppy centre axis. To resolve this I am also going to make a encoder mount making is fully mountable on most DOB's both centre axis and outer axis without major mods.
